Here I'm explaining how can we write clean code in Python which improves your coding standard and represents you as an experienced Python Developer.

Naming convention

A. Class Name

• Use grammatically correct variables and meaningful class names which represent the purpose and business logic of the class.
• The class name should start with an uppercase and must follow the camelCase convention If more than two words are to be used.

# Bad
class employeemanagement:
    pass

# Bad
class Employee_management:
    pass

# Bad
class employee_management:
    pass

# Perfect
class EmployeeManagement:
    pass

B. Function name

• Use a valid function name so it is easy to understand the purpose and business logic of the function.
• A function name should be combined with an underscore (_), and must be lowercase.
• For arguments, always use self as the first argument to declare an instance variable.
• Use cls for the first argument for the class method.

# Bad
class EmployeeManagement:
    def addemployee(self):
        pass

    def updateEmployee(self):
        pass

# Good
class EmployeeManagement:

    def add_employee(self):
        pass

    def update_employee(self):
        pass

    def get_employee(self):
        pass

    @classmethod
    def list_employee(cls):
        pass

C. Variable Names

• A variable name should start with a letter or the underscore character.

class EmployeeManagement:
    # Bad
    firstname = None
    Lastname = None

    # Good
    first_name = None
    last_name = None

    def add_employee(self, first_name, last_name):
        self.first_name = first_name
        self.last_name = last_name
